CLAUDE: Configure dev server to allow Nginx Proxy Manager access

Added devServer configuration to bind on all network interfaces,
enabling access through Nginx Proxy Manager for remote testing.

Changes:
- Set host to '0.0.0.0' (listen on all interfaces)
- Keep port at 3000

This allows the frontend to be accessed via:
- Local: http://localhost:3000
- Remote: http://gameplay-demo.manticorum.com (via NPM proxy)
